PROBLEM TO BE SOLVED: To improve the appearance of a periphery of a front face part of a game machine while improving the stiffness of a plastic front frame, and to provide a game machine extremely hard to intrude into a game region from an interspace generated between a side end surface of a front face cover member such as a thin plastic plate and the front frame. SOLUTION: On a front face part of a plastic front frame 3, a reinforcing rib part 23 is erected so as to be opposed to nearly the whole length of an upper side part and right and left side parts of an inner wall surface of a front face cover member 7 when closing the front face cover member 7. Also, a groove 82 is formed in a base end of an external sidewall 23A of the reinforcing rib part 23, and includes: a wall surface 82A inclined in an inward direction compared with a vertical surface nearly perpendicular to a surface part of the front frame 3; and a planar slope 82B extended in an outside direction with forming an acute angle from an end edge in a backside direction of the wall surface 82A. Moreover, a surface side end edge of the front frame 3 of the slope 82B is formed to locate inward compared with an internal sidewall of the front face cover member 7. COPYRIGHT: (C)2009,JPO&INPIT
